SDB:Firefox 15 crashes on exit

Situation

After an upgrade of Firefox to version 15, it always crashes when it exits.

(It's not exactly version 15 causing this but sometimes zypp reinstalls the package causing the issue on upgrades. It's also not limited to crashes on exit. By far most of the known crashes have the same cause and this fix should stabilize your Firefox again.)

Procedure

Uninstall the package "libproxy1-pacrunner-mozjs" with YaST or zypper:

zypper rm libproxy1-pacrunner-mozjs

or directly with rpm:

rpm -e libproxy1-pacrunner-mozjs

Proxy Fix

One fix that has worked on certain firefox versions is to set the proxy from automatic to direct (eg. no proxy).
